AbstractThis research study the influence of the solid loading ratio & Reynolds number on
minor losses coefficient and pressure coefficient for sudden expansion region for
two-phase flow type gas-solid through an orifice by preparing an apparatus with
solving the mass , momentum , Bernoulli equations mathematically .
An expansion area was chosen with flow cross-section changing from small to
large with area ratio (5.8) & diameters ratio (2.4) to study the changes which occur
on minor losses coefficient and pressure coefficient with different loading ratio (0)
to (1.645) . Test a different mixture flow-rates (1.02-7.8) kg/min to find the
influence of Reynolds number with ranges of (42863) to (75909) on minor losses
coefficient and pressure coefficient .
It was found that the increase in solid loading ratio reduced linearly the minor
losses coefficient and pressure coefficient for sudden expansion region , also they
depend on (Re) but with little effect .
